Recently VVildCard777 tweeted a PSA out letting those with a stock PS4 1.76 and below console who haven't updated their Firmware know not to ever allow any of THESE Sony URLs to connect to it because when they do a special piece of data in the operating system is removed. 
This comes after zecoxao's virgin PS4 OS backup comparison of the normal / JIG bank encrypted area inside the chunk at 0x9C0000.
Sony also removes the 'special piece of data' whenever a new PlayStation 4 console (regardless of OFW version) is updated from the stock version or accesses those URLs, however, currently scene developers are interested in those with untouched PlayStation 4 consoles on 1.76 and below.
He notes: "to those misunderstanding, the act of UPDATING a NEW PS4 OR letting those urls connect to a NEW PS4 removes the data."
Further detailing: "no you need virgin PS4, isolated on a network to access enc sflash data through FTP with a kernel exploit. ->/dev/sflash0s1.cryptx3b"
Here are the Sony PS4 Block URLs to never allow to access your stock / virgin PlayStation 4 from Paste.Ubuntu.com:
If anyone has a PS4 1.76 or below OFW console that has never been updated nor accessed any of those Sony URLs feel free to contact VVildCard777 to lend PS4 scene devs a hand.
